Bought a type r trans. Guy said it was all stock and worked great. Put her in, filled her up with some torco mtf.
And went for a drive and it would clunk very bad around corners. Did a lot of research on what it could be. The possibility of it being a clutch type lsd came up, I did some tests that other threads said and according to them I did not have a clutch type. So to me that meant it must be oem and prolly broken. So I had it swaped out for an ATS clutch type and what do you know I had a clutch type in there the whole time. That had an incorrect ring gear as well. The trans is great now. Proper fluid, normal click/clunk and grips great. But what kind of clutch type lsd did we pull out? Any way to know?

Pics comming in a second

 

 

any idea what kinda LSD this is? Any idea if there is any way to tell or test?

 

Looks like a KAAZ LSD unit

 

Any way to be certain? I did not inspect any markings anywhere on the unit

 

99% sure its a Kaaz unit. One way to check for sure is take a picture of the speed sensor gear and post it up here. The speed sensor gear for the Kaaz diff are different that the stock speed sensor gear. Just sold my Kaaz for that very reason (clunking/uncomfortable). Their really good for Auto X doe...

 

Also, the Kaaz diffs like kaaz fluid. helps quiet it down a bit...

 

KAAZ units will also have the speedo ring built onto the housing.

Are the bolts for the ring gear right hand thread vs the stock left hand thread bolts on a stock differential?

 

the bolts are indeed right hand thread.

not sure where to look for the speedo ring. heres some more pics. also i do not have the VSS that goes with it. but the shop did mention that there was an issue with mine with this diff.

 

Yep. Looks like a Kaaz to me. The VSS that goes with it is $120 from Kaaz just for the gear. and is smaller in diameter than the factory VSS gear.

 

Awsome, thanks. Know anyone thats wants to buy it? Lol its for sale seeing as though I dont need it.
